Final tips

Buy Hakone Free Pass + Romance Car seat at Shinjuku Odakyu (or pre-book via Klook). Do the Loop counter-clockwise to avoid bus delays. Book onsen ryokan 2-3 months ahead. If Mt Fuji visibility matters, check the morning of and adjust schedule to go up the ropeway when sky clears. And the real magic of Hakone is the post-dinner onsen at your ryokan in yukata — that's worth more than any sightseeing.
